From WaPo (via BJ) 'Slugs' Fear HOT Lanes Will End Free Rides
"Slugs fear that allowing toll-payers into the existing carpool lanes will tempt affluent drivers who now welcome passengers to drive solo instead. Corey A. Stewart (R-At Large), chairman of the Prince William Board of County Supervisors and a frequent slugger, last week called for an independent study of how the HOT lanes would affect the impromptu carpooling system. He also complained that the private companies planning the toll lanes have not fully addressed the questions and concerns of slugs and HOV drivers."
The right to be served by an impromptu carpool is an interesting theory.
